Spending on UK debit cards overseas has fallen since the start of the year, and UK Finance said that the strength of the pound was one factor.

"This decrease, in part, highlights the growing consumer preference to holiday in the UK as sterling's purchasing power abroad has weakened considerably since the Brexit vote," the body said in its monthly debit card report.

UK tourists have also been alerted to the potential risks of charges applied on the use of cards when overseas.

Shops, restaurants and cash machines are offering tourists the option of paying in pounds rather than the local currency and applying a poor exchange rate if they take up the offer.

In July, analysis for the BBC revealed that this cost UK tourists an estimated £500m a year. Currency trader FairFX found that on some transactions tourists could lose up to 10% by paying in sterling rather than the domestic currency.
